Adjustable electrical busway joint

A busway system, comprising:

• a first electrical busway section;
• a second electrical busway section, said first and said second busway sections being configured to be electrically coupled and disposed longitudinally offset from each other;
• a busway joint disposed between and operative to couple said first and said second electrical busway sections, the busway joint comprising
• a first plurality of electrically conductive splice plates disposed in spaced apart substantially parallel relationship, each splice plate of said first plurality of splice plates defining a first splice plate first retaining portion;
• a second plurality of electrically conductive splice plates disposed in spaced apart substantially parallel relationship, each splice plate of said second plurality of splice plates disposed to overlap a portion of a corresponding splice plate of said first plurality of splice plates to form an electrical joint, each splice plate of said second plurality of splice plates defining a splice plate first adjustment portion substantially longitudinally aligned with said first plurality of splice plates and operably disposed to overlap a portion of a corresponding said first splice plate first retaining portion;
• at least one first positioning member sized and configured to be operably disposed in said first splice plate first retaining portion and said second splice plate first adjustment portion;
• said first and said second pluralities of splice plates being arranged for a longitudinal movement with respect each other between a first compressed position and a second extended position.
• a third plurality of electrically conductive splice plates, disposed in spaced apart substantially parallel relationship, each splice plate of the said third plurality of splice plates defining a third splice plate first retaining portion;
• each said splice plate of said second plurality of electrically conductive splice plates further disposed to overlap a portion of a corresponding splice plate of said third plurality of splice plates to form an electrical joint, each splice plate of said second plurality of splice plates defining a splice plate second adjustment portion substantially longitudinally aligned with said third plurality of splice plates and operably disposed to overlap a portion of a corresponding said third splice plate first retaining portion;
• and
• at least one second positioning member configured to be operably disposed in said splice plate second adjustment portion and said third splice plate first retaining portion;
• said third and said second pluralities of splice plates being arranged for a longitudinal movement with respect each other between a third compressed position and a fourth extended position.
